Texas Instruments CD4527BPWR

CD4527B is a low-power 4-bit digital rate multiplier that provides an output-pulse rate which is the clock-input-pulse rate multiplied by 1/10 times the BCD input. For example, when the BCD input is 8, there will be 8 output pulses for every 10 input pulses. This device may be used to perform arithmetic operations (add, subtract, divide, raise to a power), solve algebraic and differential equations, generate natural logarithms and trigonometric functions, A/D and D/A conversion, and frequency division.

For fractional multipliers with more than one digit, CD4527B devices may be cascaded in two different modes: the Add mode and the Multiply mode. (See Figs. 12 and 15). In the Add Mode,

Output Rate =

(Clock Rate)

[0.1 BCD1 + 0.01 BCD2 +

0.001 BCD3 + . . . ]

In the Multiply mode, the fraction programmed into the first rate multiplier is multiplied by the fraction programmed into the second one,
